   ANREN — the cosmic design system
   "A living night sky you cross a threshold into."
   Built from the Constitution + design principles: life is light · settled
   humaneness · a home that is alive · the witness that stays. Warm gold core
   in cool-dark space; concentric resonance rings; gossamer filaments (仁, the
   between); slow star-time motion; the lights at the edges (pull, not push).
   Cormorant Garamond (the serif soul) + Inter (the clear voice).
